DIES FOR FORMIHNG HORSESHOES.

Specification of Letters Patent.

Patented Apr. 1, 1913.

Application filed January 30, 1912. Serial No. 674,351.

To all 'whom t may concern Be it known that I, GEORGE KURSCHUS, acitizen of the United States of America, residing at Hastings, in thecounty of Barry and State of Michigan, have invented certain new anduseful Improvements in Dies for Forming Horseshoes; and I do herebydeclare the following to be a full, clear, and eXact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in dies for forming horse shoes andmore particularlyv to such dies for welding on toe calks and finishingthe shoe and its object is to provide automatic means for severing` andwelding the toe calks; for shaping the rear portions of the shoe andforming the nail creases or grooves and in various features ofconstruction and arrangement as hereinafter more fully described andparticularly pointed out in the claims reference being had to theaccompanying drawings, in which Figure 1 is a plan view of the bed plateand lower dies; Fig. 2 a vertical section of the device on the line 2-2of Fig. 1; Fig. 3 a vertical section on the line 3-3 of Fig. 1; Fig. 4the same as Fig. 3 with the movable dies in lowered position; Fig. 5 avertical section on the line 5-5 of Fig. 1 with the movable dies inraised position; Fig. 6 the same with the movable dies in loweredposition; Fig. 7 a plan view of the horse shoe blank ready to beoperated upon by the machine; Fig. 8 a vertical section on the line 8-8of Fig. 7 g Fig. 9 a plan view of the finished shoe; Fig. 10 a verticalsection of the same on the line 10-10 of Fig. 9; and Fig. 11 the same onthe line 11-11 of Fig. 9.

Like numbers refer to like parts in all of the figures.

1 represents a suitable bed plate to be attached to any suitable punchpress.

2 an anvil plate inserted in the bed plate to support the blank wherethe toe calk is to be welded thereto.

3 are swaging dies having converging walls at each side of the heelportions of the shoe to swage the same horizontally when forced downwardbetween the punches carried with the movable die.

4 is a cleat or holder attached to the anvil plate to engage the concaveside of the toe of the shoe and overlap the same to locate tand hold theshoe in proper position upon the anvil plate.

5 is a reciprocating slide movable on the bed plate 1 in ways 6. Thisslide has an opening 7 with an inclined wall at one end engaged by awedge 22 vertically movable in the opening to move the slide toward theshoe and in proper position to bring the cutting end 8 of said slide toact as one member of a shear to sever a portion from the end of a bar ofsteel 9 to form the toe calk. This slide is provided with a longitudinalgroove to receive the said bar 9 and properly guide the same to placewith its end properly located over the toe of the shoe'.

10 is a stop to properly locate the bar endwise which stop is pivoted at11 to swing out of the way when removing the shoe after it has beenoperated upon. This stop is normally held in operative position by aspring 12 and a pin 13. The spring yields and permits the stop 10 toswing when the shoe is to be removed.

l14: is a contractile spring to move the slide 5 back out of the way ofthe shoe and 15 an adjustable screw which serves as a stop to limit thebackward movement of the slide.

16 is a head to carry the upper die, the wedge andmthe punches providedwith a suitable shank 17 to attach the same to the plunger of a punchpress (not shown). Attached to this head are two punches 18 adapted toenter between the dies 3 and force the shoe downward therebetween toswage the same and on these punches are ribs or projections 19 whichserve to form the nail creases in the shoe thus swaging the shoelaterally at the heel to make it thicker vertically and thinnerhorizontally as at 26a and forming the nail creases 3() at the sametime. This head 16 yalso carries a die :for severing and welding the toecalk having a recess 2O formed therein to shape the said toe calk and ashoulder 21 which moves downward past the toe of the shoe opposite theholder 4 and thus forms the front of the calk and also passes downwardopposite the edge of the anvil plate 2 and thus forms a fin 29 on thefront of the shoe while simul receives the lower end of this die andalso permits the escape of any surplus metal carried away by the same asit descends. The side angle of this diealso co-acts with the cutting end8 of the slide 5 to shear the bar 26 and sever the necessary metal fromthe same to form the toe calk. This head 16 also carries a springpressed plunger 23 vertically movable therein and adapted to engage thebar 9 above the slide 5 and close to the cutting edge thereof. Thisplunger is held in the head by a longitudinally movable screw 25surrounded by a spring 24 to yieldably engage the plunger with the saidbar whereby the bar is held down and kept straight when it is sheared bythe cutting end 8 oli' the slide and the side angle ot the punch. Thishead also carries a wedge 2Q having an inclined surface adapted toengage the end wall 7 of the opening 5a in the slide 5 and as itdescends moves the slide with its cutting end 8 properly located overthe front of the shoe to sever the proper length of the bar 9 to formthe toe calk.

Push bars 27 are provided vertically movable in openings in the bedplate operated by any suitable mechanism (not shown) to raise the shoeout from between the side dies 3 after it has beenoperated upon.

In ormingthe calk 28 and iin Q9 there is considerable side strain on thepunch and to take this strain a wear plate or block 1b is inserted inthe bed plate slidably engaged by the punch as it descends.

From the foregoing description the operation of my device will bereadily understood. The blank Jfor the horse shoe as shown in Figs. 7and 8 is heated to a welding heat at the toe and a forging heatthroughout the remainder. The end of the steel bar 9 is also heated to awelding heat andplaced in the slide with its end against the stop 10.The press is now operated and as the head 16 descends, the punch shearsoff the end of the bar 9 and welds it to the blank and also forms theiin 29 and calk 28. At the same time the punches 18 drive the heelportions of the shoe between the side dies 3 swaging the same andforming the nail grooves 30. As the head 1G rises again the slide 5 isretracted and the formed shoe lifted by the pushers 27 and manuallyremoved from the machine.
